IMPROVEMENT IN HOSE-COUPLINGS.

Specification forming part of Letters Patent No. 217,894, dated July 29,1879; application filed June 28, 1875.

To all whom it may concern:

Be it known that I, ANDREW J. MoRsE, of Boston, in the county of Suffolkand State of Massachusetts, have invented an Improved Hose-Coupling, ofwhich the following is a specification.

This invention relates to improvements in hose-couplings; and consistsin a tail-piece and a threaded end or coupling-section combined with andoperating a binding-ring, so that the movement of the binding-ring andtail-piece with relation to each other, by the action of thecoupling-section, causes the tail-piece and binding-ring to grasp thehose firmly between them.

The drawing represents a sectional view of a coupling provided with myimprovement.

In the drawing, (t denotes one of the coupling-sections, that oneprovided with an external screw-thread, b, to receive a coupling-sectionprovided with an internal screw thread, and adapted to fit the threadI), as usual, such internal screw-threaded section being provided with atail-piece and bindingring, corresponding with the like parts attachedto the coupling-section a. This coupling-section a, is provided with aninternal threaded part, 0, adapted to fit the screw-threaded end of thetail-piece (1, provided on its outside with a projection, 6, extending,preferably, entirely around the lower portion of the tail-piece and thetail-piece may also be provided or not with other annular grooves orprojections between the projection e and the screw-threaded part c.

The binding-ring f is shown as a tapering ring, being larger at bottomthan at top, and being preferably provided with a shoulder at its upperend to meet a shoulder 011 the lower end of the coupling-section a. Thetail-piece might also be made tapering, growing larger at or toward itslower end.

The tail-piece (I will be inserted within the hose, and then thebinding-ring f will be placed over the end of the tail-piece and downontothe hose, and then the coupling-section a will be screwed on thetail-piece. This action will cause the lower part of thecoupling-section to force the binding-ring f down on the outside of thehose, and will closely confine the hose between the binding ring andtail piece, the projection c embedding itself into the substance of thehose, as indicated.

The hose used in connection with this ooupling may be of any well-knownor suitable manufacture or class, such as leather, cloth, india-rubber,or compounds of either with the other.

In my invention the binding-ring is forced down to bind the hose'; andthe gist of this invention is that the binding-ring is operated by thecoupling-section.

I do not desire to limit myself to the exact construction of the partsshown, and may use any equivalent.

I claim The coupling-section, provided with an internal shoulder andinternally screw-threaded to engage the tail-piece, combined with theexternally screw-threaded tail-piece and the external binding ring, f,to operate as shown and described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

ANDREW-J. MORSE.
